Diagnostic insights and updates

H3N2 canine influenza virus was first detected in the United States in the spring of 2015 when a severe respiratory outbreak occurred in the Chicago region. Since then, the virus has continued to spread across the United States causing local outbreaks.

This particular strain has demonstrated greater virulence, greater infectivity, and prolonged shedding when compared to the H3N8 canine influenza strain, and it has also been reported in shelter cats. H3N8 canine influenza vaccines are not effective against H3N2, but new H3N2 vaccines are now available in the United States. Secondary bacterial pneumonia and coinfections can be seen with influenza.

Accurate diagnosis is critical in the prevention and management of canine influenza outbreaks. A comprehensive respiratory RealPCR panel on respiratory swabs taken early in the clinical course of infection is recommended for diagnosis of influenza and coinfections. Learn more about canine influenza so that you will be prepared in the event that the H3N2 outbreak reaches your patients.
